Find the central value of the above data by the following methods.

Arithmetic Mean (from actual data, grouped frequency data, compare the result

of these two methods)

Geometric Mean (grouped frequency data)

Harmonic Mean (grouped frequency data)

Mode (grouped frequency data)

Quantiles (grouped frequency data).

If np 25 and nq 2 5, estimate P(at least 2) with n=13 and p= 0.4 by using the normal distribution as an approximation to the binomial distribution; if np <5 or nq<5, then state that the normal approximation is not suitable. Select the correct choice below and, if necessary, fill in the answer box to complete the choice. O A. P(at least 2) = (Round to three decimal places as needed.) O B. The normal distribution cannot be used.

1. A) The probability of surviving 2 years after being diagnosed with a slow-progressing form of prostate cancer is .85.
2. B) The probability of surviving 2 years after being diagnosed with a slow-progressing form of prostate cancer is .85 for the individuals being followed in this study.
3. C) The probability of surviving 2 years after being diagnosed with a slow-progressing form of prostate cancer is .85 for individuals who decided against all forms of treatment.
4. D) The probability of surviving 2 years after being diagnosed with a slow-progressing form of prostate cancer is .85 for the individuals being followed in this study and for individuals who decided against all forms of treatment.
